Edit Question
Title
Body
This (simplified version of my code) doesn't work: <?php $sxml = new SimpleXMLElement('<somexml/>'); function foo(){ $child = $sxml->addChild('child'); } foo(); ?> Why? I want to access $sxml because I want to log errors on it if foo() fails. foo() calls itself recursively to create a directory listing, so I fear passing the whole $sxml onto itself (as in foo($sxml) ) could hurt performance. Is there a way to access $sxml inside $foo without passing it as an argument? (PHP 5.2.x+) EDIT: What if the code looks like this, actually? <?php bar(){ $sxml = new SimpleXMLElement('<somexml/>'); function foo(){ $child = $sxml->addChild('child'); } foo(); } bar(); ?>
